ANGLE-COCK.

Specification of Letters Patent.

Patented Feb. 23, 1909.

To all whom it may concern:

Be it known that we, WILLIAM B. HEINI- GER and WILLIAM E. VALLANGE,citizens of the United States, and residents of Jersey City, county ofHudson, and State of New Jersey, have invented certain new and usefulImprovements in Angle-Cocks, of which the following is a full, clear,and exact description.

This invention relates more particularly to angle cocks for air-brakesystems of railway cars.

The primary object of the invention is to provide simple and eilicientmeans whereby the operating handle of the cock may be positively lockedin either an open or a closed position in such a way that the handlecannot-'bershifted or moved accidentally as is the case with valves ofthis class as ordinarily constructed.

A further object of the invention is to provide simple means which maybe readily attached to the ordinary form of handle, and which must bemanually moved before the operating handle of the plug can be moved fromeither an open to a closed position, or from a closed to an openposition.

lVith these and other objects in view, the invention will be hereinaftermore particularly described with reference to the accompanying drawings,which form a part of this specification, and will then be pointed out inthe claims at the end of the description.

In the drawings, Figure 1 is a side elevation of one form of valve orcock embodying our invention. Fi 2 is a plan view with the handle removeFig. 3is a fragmentary detail plan view of the handle. F 1g. 4 is afragmentary end view, partly in section, showing the position of thelocking means when the handle is held against movement. Fig. 5 is a sideelevation showing a different application of the locking means to adifferently constructed handle; and Fig. 6 is a plan view of the deviceshown in Fig. 5.

The casing 10 which may be attached to the usual train-pipe, forming apart of the usual air-brake system may be of any suitable form, and ofany desired construction, and within the casing is a movable member orlug l1.Y This plug 11 may be provided Wit 'asquare or other shankor'part 12, and

on this shank 12 is held an operating device 13. The operating devicehas a handle 14 and a head 15, and in said head is an opening 16,corresponding to the shape of the shank 12, and projecting outward anddownward from the head l5 is the operating handle 14, by which the plugof the cock may be moved to an open or a closed position in the usualway. The head l5 is provided with lugs 17 and 18 on opposite sidesthereof, and between the lugs 1S is pivotally held a pawl or lockingdevice 19, as at 20, and between the lugs or ears 17 is pivotally held,at 21, a similar pawl or locking device 22. Each pawl has a pendentportion 23, and an enlarged operating portion 24, by which the saidpawls may be moved on their pivots 2O and 21. The weight of the pendentportion 23 of each pawl is sutlicient, however, to cause the said pawlsto normally assume the positions indicated in Figs. 1 and 4, under theinfluence of the force of gravity. The handle 14 is provided with asuitable stop 25 adjacent the head 15, and the same may be secured tothe operating device or formed integral therewith as desired.

The casing 10 is provided with lugs 26 and 27 which extend outwardlytherefron'i, and are so positioned that when the stop 25 of theoperating device 13 is moved it will engage one face of either of thelugs 26 and 27, according to whether the handle 14 is moved to the openor to a closed position. When the stop 25 on the operating deviceengages the lug 27 on the casing, the plug should be in an openposition, and in this position the pawl 22 is made to engage the face ofthe lug 26 next to the lug 27, and thereby hold and lock the handle inthis position. If the handle is moved so that the stop 25 engages thelug 26, then the pawl 19 is raised sufficiently to pass by the lug 27 onthe casing, and when in this position is then moved downward so that itspendent end 23 will engage the lug 27 and thereby prevent movement ofthe handle in either direction. By this means the handle of theoperating device may be rigidly held to the plug so as to rotatetherewith, and by means of the pawls 19 and 22, the said operating meansand its handle, together with the plug connected therewith, will bepositively locked in either theclosed or 'an open position, so

as to prevent accidental movement of saidV operating device.

ln the construction shown in Figs. 5 and 6 the operating device 2Scomprises two members 29 and 30. The member 29 is secured to the shank31 of the plug, and has a projecting lug 32, which is pivoted at 33 tothe handle member of the operating device 28. This handle member 30 hasa head 311, and projecting from the head is the operating handle 35. Thehead 34 is provided with a slot 36 so as to permit a lug or stop 37 topass through the same, the said stop being carried by the member 29, andbeing adapted to engage the lugs 26 and 27 of the casing insubstantially the same manner as the stop 25 of the operating device 13.The head 34 is provided with two lugs or fixed pawls 38 and 39, whichare adapted to alternately engage either of the lugs 26 and 27 when theother lug is engaged by the stop carried by the member 29. In thisconstruction it is necessary to lift the handle upward on its pivot torelease either of the lugs 38 and 39, or raise the same above the lugs26 and 27 before the handle can be rotated. The construction thus fardescribed of Figs. 5 and 6 is of the usual construction, and is notbroadly claimed herein.

To prevent the handle from being raised accidentally, as by a stone fromthe ballast of the railroad, or by any other accident which might raisethe handle and thereby permit the same to operate the plug resultingthereby in a possible accident, we pivot to the member 29 on each sideof the stop the pawls 40 and 41. These pawls are pivoted, at 42, to themember 29, and when in the position shown in Fig. 5, the handle cannotbe raised unless the pawls are released, and therefore, the cocK cannotbe moved accidentally as would be the case if the pawls were not used.If the pawls are released so that the handle can be raised, the lugs onthe head of the operating device can be lifted above the lugs 26 and 27to permit the operating handle to be moved, and the pawls can then bemoved to a position to lock the handle against verticalmovement andthereby prevent the operating handle from being moved.

From the foregoing it will be seen that simple and efficient means isprovided whereby an operating device may be applied to the usual form ofangle cock or other fitting in such a way that the operating handle mayhave a rotary movement, and may be positively locked and held in eitheran open or a closed position; that the said means may be applied to theusual form of fitting; and that the locking pawls may be applied to theoperating handle with very little additional expense, and at the sametime insures absolute safety from accidental movement of the operatinghandle.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent 1.
